Because the nation of Sanadia resisted the Harmonian annexation of the region, their citizens were reclassified as 3rd Class Citizens under Harmonian law and all Sanadian children were sent to Crystal Valley to be raised as Harmonians.

Despite their resistance towards the Harmonian invasion, by the year 452, the majority of people in Sanadia had become integrated into Harmonian society. Nowadays, Sanadia functions as a relatively inconsequential Harmonian province.
